The Tale Of Timothy Turtle in "Careful Mr. Frog"

"Certainly!" Mr. Frog replied. And he began to mutter, as if to himself, "J. G.—that means just grumpy, of course——"

Timothy Turtle interrupted him quickly.

"I don't care to hear any more," he screamed. And turning away, he waddled towards the water.

"That Ferdinand Frog has no manners," he spluttered. "I only wish he wasn't quite so spry." And Mr. Turtle looked very fierce as he snapped his jaws together.
